fuel filter help!!!please!

so i tried replacing my fuel filter. i got rid of the pressure then sprayed some pb blaster to loosen the bolts. i got the bolt on the right side off easy but i stripped the one on the left so i used vise grips. the vise grips got grip but now the side of the fuel filter is bent and i think its leaking a little gas!

is it the nut on the fuel line that is stripped or the back-up nut on the filter itself cause you should be able to turn the one that is away from the filter and back-up the one on the filter that's what I just did hopefully you don't need a new line
